I wonder how they implemented pressure sensitivity in garage band drums, I can't find any mention of pressure sensors in the screen.

My guess is that they are using the gyro for this. Is it a good guess?

According to the TC live blog: "Very neat; you can tap keys hard or soft to determine how the note comes out, thanks to some accelerometer magic"

My guess: fingers are soft, and more pressure means a wider area of finger is in contact with screen, and that's what they're detecting.

But sensing the vibration of a more vigorous touch would be interesting, too!
